Serial No. 222,035."

This invention relates in general 4to a device for protecting vaults and the like, and more particularly to'a device adapted to protect the vault by means of air contaminating gases, such as tear gas or the like, and it has ior an object the provision for the removal of thev gas bomb during working hours, or the users discretion, so as to prevent an accidental discharge of the gas bomb.

'Another important object o1"- `the invention is to provide such a device constructed 'to facilitate thev removal of the bomb without the use of tools, and without danger' of exploding or releasing the bomb.

Another important object oi the invention is to provide such a device which will be Vsimple in design, eiiicient operation and which may be economically manufactured.

Another important object of the invention so is to provide a foolproof and dependable liring mechanism for devices of this character.

Numerous other objects and advantages of the invention will be apparent as it is better' understood Jrrom the following description,

which, taken in connection with lthe accompanying drawings, discloses apreterred eni-v bodiment thereoi. l

Referring to the drawings:

Figure l is an elevational view oi the :inside of a vault door and showing a device embodying my invention secured thereto in operative position;

Fig. 2 is a perspective view of the -bomb container, with parts thereoi` separated to :ai show details of construction;

Fig. 3 is a section al view taken substantially on line 3-3 in Fig. l and showing the relative normal position of all of the parts;

Fig. 4 is a similar view, showing the firing 4e pin released and into a bomb discharging condition;

Fig. 5 is a perspective view et' the tiring pin holding device; and

Fig. 6 is a perspective view of the iring pin.

While this invention is capable of employment for the protection of compartments of various sizes and characters I have shown it embodied in a device particularly adapted ior v50 attachment to the door 11 of a vault. rlhe bomb 16 is carried in av container l2 sup-` ported onthe door 1l. A cord or strand i8 is arranged over the ma] or part or the door surface and adapted to normally prevent.V

operation ot the bomb vtiring mechanism and permit operation thereoitv when an attempt is made to burn, out or break through the surface o? the door to gainentrance to the vault.

j ne receptacle l2 includes a part le and a partiti. ihe part i4 oi the receptacle l2 may be oi any suitable form adapted to contain a bomb 16 of any suitable type of air contaminating device and adapted to .be diss. charged by impact. In the present instance l have shown a Vusual type of tear gas bomb,

provided with mechanism for releasing the gas upon impact delivered to a plunger 17 car- V" n its top. 'The part le in the present kis ont tubular form and is provided ottoni closure 18. lt has a plurality oi bayonet slots i9 in its top and a plurality ot vappropriately arranged openings2l to permit the escape of gaswhen generated or discharged by the bomb. The receptacle part is generally in the form oi' a cap adapted to close the upper end oi the part le and support the entire device. lt is provided with a bracket formation 22 at its rear adapted to receive a plurality of screws 23 or like fastening devices ifor attaching the part l5 tothe door. Y

.A pair of oppositely disposed shoulderpins 25 are driven into suitable apertures in the part l5 and are adapted toV engage in the bayonet slots i9 oi the part le. The preferred threaded engagement in the closure 28.`

wNithin the sleeve 26 and at a slight distance trom* an inner end 3e of the closure 28 an (ill annular' wall 35 is secured in any suitable manner to provide a spring seat.

The firing pin may be of any suitable form and size and in the present instance I have shown such a pin having a large cylindrical portion 3G of a size permitting a free sliding lit within the sleeve 26; a portion of reduced diameter 37 above the portion 36 and providing a shoulder' 38; a tapered neck portion 39; and a head portion 41 providing a shoulder 42. The normally compressed spring 31 tor actuating the firing pin is disposed about the tiring pin part 37 between the spring seat 35 and the shoulder 38.

rlhe device 32 may be any suitable means for holding the liring pin in the retracted position and releasing the tiring pin upon disturbance of the cord 13. ln the preferred embodiment shown on the drawing this comprises a pin having a sliding tit through the closure 23. This pin 43 carries a plurality ot' hooks 44 pivotally connected thereto by means of a pin 45 and positioned in a slot 46 in an end thereof. The end of the pin 43 opposite the hooks 44 is formed in any suitable manner to facilitate the attachment of the strand 13. l have shown this end slightly cut away and apcrtured at 47 to receive a ring to which tue strand 13 may he attached. "i'he pin 43 is preferably lapertured at 4S) to receive cotter pin or like device for locking the firing pin in retracted position during shipment or when the device .is not in operation. The hooks 44 are prelirerably cut or punched from platestoclr and formed to engage the shoulder 42 ot the firing pin as shown (Fig. Y

rlfhe pin 43 is pulled normally to the top oi sleeve 26 by springs 53 interposed in the strand or cord 13 this cord being freely trained over pulleys The springs eX- ert a pull on the pin 43 greater in force than that ol" spring 31 when the parts are in door protecting relation. rlfhe hooks 44 are engaged with the shoulder 42 oit the liring pin head 41 by pushing the liring pin up into the sleeve 26 and the cord is attached. rlhe pull on the cord 13 now holds the tiring pin retracted and shoulders 51 which are provided on the hooks are engaged with the bottom 34 of sleeve closure 28. This engagement positively7 holds the hoolrs in engagement with the tiring pin and prevents accidental discharge.

`When the cord is broken the spring 31 forces the firing pin 29 downwardly moving the pin 43 with it until the shoulders 51 en-4 gagerthe spring seat member 35. This engagement pulls the hoolrs 51 outwardly and permits the spring 31 to force the firing pin on down to lire the gas bomb.

It will be apparent that the container part 14 with the gas bomb may be readily removed when protection of the vault is not needed by merely detaching the parts 14 from the part 15, thus preventing accidental discharge while the vault is open for legitimate purposes. This removal in no way need disturb the cords or firing pin unit and the whole assembly may be rendered operative once more by merely reconnecting the container part 14 with its bomb into the cap part 15.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing' description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts, without departing from the spirit and scope oi' the invention, or sacrificing all of its material advantages the form hereinbctore described being merely a preferred embodiment there-ot'.

I claim:

A vault protecting device, con'iprising devices adapted tor disturbaiice upon attempted unauthorized entry into the vault, an automatic discharge mechanism ciated with and controlled by said devices, said discharge mechanism including a movable .supporting pin, expansible shouldered hook jaws attached to said supportiiw pin, a capped tiring pin said jaws adapted to engage the cap ot tiring pin, a spring support on said hring pin, a spring seat in said discharge mechanism, a spring located between said spring support and spring seat, the upper surface oli' said spring seat constructed and located to arrest the movement oi said aws and to open the same and release said liring pin, said spring arranged to drive said released tiring pin toward a bomb and lire the same.
